Madeline Perry has announced her retirement from the WSA World Tour and will make her farewell Tour appearance at the Gillen Markets Irish Open later this month in Dublin.
Perry, however, said she will continue to represent Ireland.
A full-time professional since 1999, 38-year-old Perry has enjoyed a distinguished career in the sport, winning 11 WSA Tour titles from 27 final appearances and celebrating a career-high world No.3 ranking in 2011.
The Australian Open champion in 2010 in Canberra - where she upset both the second and third seeds en-route to the WSA World Series title - the Banbridge-born star has won the prestigious Irish Open trophy five times, twice finishing as runner-up.
With more than 120 caps for Ireland, Perry has competed for her country in eight successive biennial World Team Championships and in February won a record 15th Irish National title.
"I have decided to retire from the World Tour and have decided that the Irish Open (from 21-25 April) will be my last World Tour event," said Perry, the event's top seed for the ninth time.
"It is been an incredibly difficult decision to make but I had to be honest with myself and unfortunately I have noticed that I do not have the same extreme focus that I once had, or indeed, desire to compete.
"Having had such a successful career, I felt that I was no longer doing myself justice and felt the time was right to move on and find a new career."
She added: "I still play and train to a very high level so I have every intention of continuing to compete for Ireland, at national level and leagues as I still love training and playing the game.
"I also hope to coach more and give back to the sport that has given me so much."
Irish Squash president Ed Dunne said: "Madeline has been a great role model for squash players in Ireland and around the world playing a such a high level for so many years.
"We in Irish Squash are so proud of her and thank her for all that she has contributed to squash in Ireland.
"I want to wish her all the best in the next chapter of her life and we are delighted that she will continue to play squash at national level."
